2. First law of thermodynamics - Wikipedia

   en.wikipedia.org/wiki/First_law_of_thermodynamics

   The first law of thermodynamics for closed systems was originally induced from empirically observed evidence, including calorimetric evidence. It is nowadays, however, taken to provide the definition of heat via the law of conservation of energy and the definition of work in terms of changes in the external parameters of a system.

3. Energy - Wikipedia

   en.wikipedia.org/wiki/Energy

   There is a fact, or if you wish, a law, governing all natural phenomena that are known to date. There is no known exception to this law – it is exact so far as we know. The law is called the conservation of energy. It states that there is a certain quantity, which we call energy, that does not change in manifold changes which nature undergoes.

4. Energy law - Wikipedia

   en.wikipedia.org/wiki/Energy_law

   Energy laws govern the use and taxation of energy, both renewable and non-renewable. These laws are the primary authorities (such as caselaw, statutes, rules, regulations and edicts) related to energy. In contrast, energy policy refers to the policy and politics of energy. Energy law includes the legal provision for oil, gasoline, and ...

   The series was originally planned to consist of 26 episodes. [13] [14] This was later expanded to 60 episodes, a number then cut back to the eventual total of 52 for budget and production-schedule reasons. [2] [15] The show was intended not to require previous experience with calculus.

7. Second law of thermodynamics - Wikipedia

   en.wikipedia.org/wiki/Second_law_of_thermodynamics

   The second law of thermodynamics is a physical law based on universal empirical observation concerning heat and energy interconversions. A simple statement of the law is that heat always flows spontaneously from hotter to colder regions of matter (or 'downhill' in terms of the temperature gradient).

8. Conservation law - Wikipedia

   en.wikipedia.org/wiki/Conservation_law

   In physics, a conservation law states that a particular measurable property of an isolated physical system does not change as the system evolves over time. Exact conservation laws include conservation of mass-energy, conservation of linear momentum, conservation of angular momentum, and conservation of electric charge.

9. Energy Act 2010 - Wikipedia

   en.wikipedia.org/wiki/Energy_Act_2010

   The Energy Act 2010 (c. 27) is an act of the Parliament of the United Kingdom pertaining to the regulation of energy usage and markets, with amendments to similar pieces of previous legislation. The act was granted royal assent on 8 April 2010 along with a series of other bills during the wash-up period prior to the 2010 general election .
